摘要：
The aim of this work is to present a damage identification method dedicated to beams. The core of the approach is the Virtual Distortion Method, which is a fast reanalysis method successfully applied to damage identification. Loss of stiffness and mass are modelled by virtual distortions and modifications of the parameters are calculated as a result of a sensitivity-based minimisation. In this paper we deal with a steady-state problem i.e. low frequency, non-resonance harmonic excitation induces a static-like structural response with virtual distortions (design variables) modelling parameter modifications.
